+.Sh NAME
+.Nm bge
+.Nd "Broadcom BCM570x PCI gigabit ethernet adapter driver"
+.Sh SYNOPSIS
+.Cd "bge* at pci? dev ? function ?"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for various NICs based on the Broadcom BCM570x
+family of gigabit ethernet controller chips, including the
+following:
+.Pp
+.Bl -bullet -compact
+.It
+3Com 3c996-T (10/100/1000baseTX)
+.It
+Dell PowerEdge 2550 integrated BCM5700 NIC (10/100/1000baseTX)
+.It
+SysKonnect SK-9D21 (10/100/1000baseTX)
+.It
+SysKonnect SK-9D41 (1000baseSX)
+.El
+.Pp
+All of these NICs are capable of 10, 100 and 1000Mbps speeds over CAT5
+copper cable, except for the SysKonnect SK-9D41 which supports only
+1000Mbps over multimode fiber.
+The BCM570x builds upon the technology of the Alteon Tigon II.
+It has two R4000 CPU cores and is PCI v2.2 and PCI-X v1.0 compliant.
+It supports
+.\"IP, TCP
+.\"and UDP checksum checksum offload for both receive and transmit,
+multiple RX and TX DMA rings for QoS applications, rules-based
+receive filtering, and VLAN tag stripping/insertion as well as
+a 256-bit multicast hash filter.
+Additional features may be provided via value-add firmware updates.
+The BCM570x supports TBI (ten bit interface) and GMII transceivers, which
+means it can be used with either copper of 1000baseX fiber applications.
+Note however the device only supports a single speed in TBI mode.
+.Pp
+Most cards also use the Broadcom BCM5401 or BCM5411 10/100/1000
+copper gigabit tranceivers,
+which support autonegotiation of 10, 100 and 1000mbps modes in
+full or half duplex.
+.\".Pp
+.\"The BCM5700 also supports jumbo frames, which can be configured
+.\"via the interface MTU setting.
+.\"Selecting an MTU larger than 1500 bytes with the
+.\".Xr ifconfig 8
+.\"utility configures the adapter to receive and transmit jumbo frames.
+.\"Using jumbo frames can greatly improve performance for certain tasks,
+.\"such as file transfers and data streaming.
+.Pp
+The
+.Nm
+driver supports the following media types:
+.Bl -tag -width 10baseTXUTP
+.It Cm autoselect
+Enable autoselection of the media type and options.
+The user can manually override
+the autoselected mode by adding media options to
+.Xr rc.conf 5 .
+.It Cm 10baseT/UTP
+Set 10Mbps operation.
+The
+.Xr ifconfig 8
+.Ic mediaopt
+option can also be used to select either
+.Cm full-duplex
+or
+.Cm half-duplex
+modes.
+.It Cm 100baseTX
+Set 100Mbps (fast ethernet) operation.
+The
+.Xr ifconfig 8
+.Ic mediaopt
+option can also be used to select either
+.Cm full-duplex
+or
+.Cm half-duplex
+modes.
+.It Cm 1000baseTX
+Set 1000baseTX operation over twisted pair.
+.Cm full-duplex
+and
+.Cm half-duplex
+modes are supported.
+.It Cm 1000baseSX
+Set 1000Mbps (gigabit ethernet) operation.
+Both
+.Cm full-duplex
+and
+.Cm half-duplex
+modes are supported.
+.El
+.Pp
+The
+.Nm
+driver supports the following media options:
+.Bl -tag -width full-duplex
+.It Cm full-duplex
+Force full duplex operation.
+.It Cm half-duplex
+Force half duplex operation.
+.El
+.Pp
+The
+.Nm
+driver also supports one special link option for 1000baseTX cards:
+.Bl -tag -width link0
+.It Cm link0
+With 1000baseTX cards, establishing a link between two ports requires
+that one port be configured as a master and the other a slave.
+With autonegotiation,
+the master/slave settings will be chosen automatically.
+However when manually selecting the link state, it is necessary to
+force one side of the link to be a master and the other a slave.
+The
+.Nm
+driver configures the ports as slaves by default.
+Setting the
+.Cm link0
+flag with
+.Xr ifconfig 8
+will set a port as a master instead.
+.El
+.Pp
+For more information on configuring this device, see
+.Xr ifconfig 8 .
+.Sh DIAGNOSTICS
+.Bl -diag
+.It "bge%d: couldn't map memory"
+A fatal initialization error has occurred.
+.It "bge%d: couldn't map ports"
+A fatal initialization error has occurred.
+.It "bge%d: couldn't map interrupt"
+A fatal initialization error has occurred.
+.It "bge%d: no memory for softc struct!"
+The driver failed to allocate memory for per-device instance information
+during initialization.
+.It "bge%d: failed to enable memory mapping!"
+The driver failed to initialize PCI shared memory mapping.
+This might
+happen if the card is not in a bus-master slot.
+.It "bge%d: no memory for jumbo buffers!"
+The driver failed to allocate memory for jumbo frames during
+initialization.
+.It "bge%d: watchdog timeout"
+The device has stopped responding to the network, or there is a problem with
+the network connection (cable).
